The study analyses, the perception of the European City of Science (ECS) initiative planned event in Katowice in the context of the city and region's development in the eyes of private companies. It has been argued that this honour may change the city's prestige and become the source of the city and the region's development, not only through building the city's recognisable brand but also its social capital. Using focus research as a method enables not only to collect empirical data but can also be treated as a form of public participation. The study results contribute to the growing body of literature on public engagement and co‐creation as well as place branding. The study's findings show the companies' expectations concerning the role of universities and their participation in the region's development. They were the foundation for preparing a set of suggestions for local governments to successfully implement the ECS initiative. This paper is the first to examine the process of preparing a city to become an ECS, as demonstrated through the case study of Katowice.
